Republican lawmakers will overturn a key piece of the Affordable Care Act in their tax overhaul, a victory in a long GOP campaign against the health law.

Senate Majority Leader Mitch McConnell said the compromise tax bill from House and Senate negotiators will end the health law’s requirement that all individuals buy insurance or pay a fine.

The bill will “repeal Obamacare’s individual mandate tax, delivering relief to low- and middle-income Americans who have struggled under an unpopular and unworkable law,” the Kentucky Republican said in an emailed statement.
